Application mea March 29, 1918.

To all whom t may concern Y Be it knownl that I, CHARLES C. BLAKE, a citizen of the YUnited States, residing at Brookline, in the county of Norfolk and State of Massachusetts, have invented certain Improvements in W'elting, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several ligures.

The present invention relatesto welting which is used in the manufacture of welt shoes, and more particularly to welting used in the manufacture of Blake welt shoes.

In making a Blake welt shoe there are twooperations which particularly distinguish from the manufacture of Goodyear welt shoes. These operations are lasting and inseam sewing. In the lasting' operation the upper is updrawn to stretch the upper to the wood of the last and then the stretched upper is secured to the edge face of an insole on the bottom of the last. In the inseam sewing` operation a welt is secured to the lasted shoe so that the iiesh faces of the welt and insole are in the same plane.

The object of the present invention is to produce a welt for a welt shoe by means of which a better joint can be made between the upper of the lasted shoe and the edge face of the welt engaged thereby.

To the accomplishment of this object, and

such others as may hereinafter appear, the` features of the invention relate to certain constructions, arrangements and methods of manufacture hereinafter described and then set forth broadly and in detail in the appended claims which possess advantages readily apparent to those skilled in the art.

The various features of the present invention will be readily understood from an inspection of the accompanying drawings, in which,

Figure 1 is a perspective of a strip of welt# ing embodying the features of the present invention, and L F ig. 2 is a sectional elevation illustrating the operation of attaching the welt shown in Fig. l to a Blake lasted welt shoe.

In the manufacture of a Blake welt shoe an insole 1 is secured to the bottom 2 of a last 3 and an upper 4 is stretched on the top of the last and then secured in its stretched condition to the edge face' of the insole.

Specification of Letters Patent.

Patented Mar. 7, 1922. Serial No. 225,572.

The next operation is the inseam sewing operation wherein a welt 6 is secured to the lasted shoe. To this end the welt 6 is provided with a longitudinal slit 7 formed alon the edge face 8 which is exposed in the nished shoe. The welt is secured to the lasted shoe by a single thread 9 passing through the welt, upper and insole and anchored in the base of the slit 7 of the welt and on tongues l0 formed in the iiesh face of the insole.

I-Ieretofore the'edge face of the welt which engaged the upper 3 of the lasted welt shoe was normal to the top and bottom faces of the welt. With this construction it was discovered that after the welt was secured to the lasted shoe the edge face of the welt had become convex owing to the bulging of the leather caused by the introduction of the stitches. This convex edge face of the welt allowed the welt to rock on the upper and somewhat affected the appearance of the joint between the weltl and the upper.

To avoid this diiliculty I propose to concave the edge face l1 of the welt engaged by the upper as shown at 12, Fig. l. With this construction when the welt is drawn up tight against the lasted welt shoe the edge face ll becomes normal to the top and bottom faces of the welt thus making a good joint with the upper. c

. I propose to provide the welt 6 with the slit 7 and concave l2 simultaneously as in that way the tendency of the slitting and cencaving tools to distort the' welt may be counteracted.

While it is preferred to employ the specific construct-ion, arrangement and method of manufacture shown and described, it will be understood that this specific construction, arrangement and method of manufacture is not essential nor is the conjoint use of all the features of the invention essential except so far asy specified in the appended lclaims and it may be varied or modified without departing from the broader features ofV the invention. y

What is claimed as new, is:

l. A welt for a welt shoe provided with a concaved edge face, the top and bottom edges of said concaved edge face lying in the same vertical plane of the welt.

2. A welt for a welt shoe provided with a concaved edge face,

the top and bottom parallel to the other edge face edges'of Seid oonoeved edge ieee lying n the sinne vertleal plane parallel to the other edge face of the Welt, sand conoeved edge face be- `ing opposite the edge face of the Welt which is exposed in the linshedslloe.

3. A Welt for a Welt shoe provided with a longitudinal slit along the edge face which is exposed Aneme to this' specification. in the nshed shoe and having Y v that edge fece which is opposite the slit edge V fece oonoeved.V Y l y 4f. A Welt for a. Welt shoe having plain top and bottom feces and edge 'faces slit and conoaved longitudinally, respectively.

In testimony whereof l have signed my CHARLES I o. BLAKE.
